A nurse is visiting a client who has Alzheimer's disease in their home. The client's spouse states that the client gets increasingly agitated and restless in the evening hours and can sometimes be difficult to calm down. Which of the following behaviors does the nurse recognize that the client is experiencing?

A. Apply soft restraints to wrists and chest: Using restraints should only be considered as a last resort and should not be the first intervention for managing delirium. Restraints can exacerbate agitation and increase the risk of complications such as skin breakdown, musculoskeletal injury, and psychological distress. Therefore, applying restraints should not be the first action taken by the nurse.

B. Administer antipsychotic medications as prescribed: While antipsychotic medications may be used to manage symptoms of delirium in some cases, they should not be the first intervention for preventing client injury. Additionally, the use of antipsychotics in the ICU requires careful consideration due to potential adverse effects, such as sedation, hypotension, and prolongation of the QT interval. The decision to administer antipsychotic medications should be based on a comprehensive assessment and in consultation with the healthcare team.

C. Administer sedative medications as prescribed: Administering sedative medications may help calm an agitated client with delirium, but it should not be the first intervention for preventing client injury. Sedatives can further impair cognition and increase the risk of falls or other complications. Like antipsychotic medications, the use of sedatives should be based on a thorough assessment and in collaboration with the healthcare team, rather than being the initial action taken by the nurse.

D. Arrange for one-on-one observation for the client: Delirium in the intensive care unit (ICU) is a serious condition that can lead to confusion, disorientation, and an increased risk of injury to the client. The priority intervention for preventing client injury in this situation is to ensure constant monitoring and supervision. By arranging for one-on-one observation, the nurse can provide continuous monitoring of the client's behavior, assess for changes or signs of agitation, and intervene promptly to prevent falls or other injuries.

A. "Vision changes occur when the retina begins to breakdown and collect bits of debris": This statement does not accurately describe the changes that occur in the eye during retinal detachment. Vision changes in retinal detachment primarily occur due to the separation of the retina from its underlying tissue layers, rather than the breakdown and collection of debris within the retina.

B. "Vision changes occur when retinal tissue pulls away from the blood vessels in the eye": Retinal detachment occurs when the retina, which is the light-sensitive layer at the back of the eye, pulls away from its normal position along the inner wall of the eye. This separation disrupts the blood supply to the retina, leading to vision changes. The most common symptom of retinal detachment is the sudden appearance of floaters or flashes of light in the visual field, followed by a shadow or curtain effect as the detachment progresses. Therefore, this statement accurately describes the pathophysiological mechanism underlying vision changes in retinal detachment.

C. "Vision changes occur when the cloudy lens alters the passage of light through the eye": This statement describes changes associated with cataracts, not retinal detachment. Cataracts involve clouding of the lens inside the eye, which can lead to vision changes such as blurriness or decreased visual acuity. However, cataracts are distinct from retinal detachment, which involves the separation of the retina from the inner wall of the eye.

D. "Vision changes occur suddenly due to complete obstruction of aqueous humor outflow": This statement describes the pathophysiology of acute angle-closure glaucoma, not retinal detachment. Acute angle-closure glaucoma is characterized by sudden elevation of intraocular pressure due to complete obstruction of the outflow of aqueous humor, leading to rapid onset of symptoms such as severe eye pain, blurred vision, and halos around lights. Retinal detachment, on the other hand, is characterized by the separation of the retina from its normal position, resulting in distinct vision changes such as floaters, flashes of light, and visual field defects.
